Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a main block diagram illustrating a device according to the present invention. FIG.

As shown in the drawing, in the present invention, when the cutting chips 2 are inserted into the hopper 1, the cutting chips 2 are cut by the rotation of the screws 3 and gathered at the center. In this case, not only the chip 2 but also a metal such as a spanner or the like, which is mistakenly inserted in the work, or a waste such as a round bar after the work of the lathe may be put together or entered incorrectly. These are also cut by the screw 3 and gathered in the center. A screw structure capable of centering operation will be described later.

A discharge port 4 is formed at the center lower portion and a pressure cylinder 50 is installed at the upper portion thereof so as to be able to push the chips 2 by the piston. The pressure cylinder 50 is required because the chips enter the discharge port 4 without forming the pressure cylinder 50 and the chips are formed in a meandering shape and occupy a large volume and can not be smoothly injected.

The chips 2 discharged into the discharge port 4 are compressed in the horizontal direction by the piston 8 of the compression cylinder 7. That is, when the compression door 13 is closed, the blocking door 13 is closed, and after the compression is completed, the blocking door 13 is raised and the piston 8 of the compression cylinder 7 is advanced to discharge the compressed mass 10. The discharged compressed lobes 10 are transported on the conveyor 14. Although the transporting direction is shown as being transported to the upper part in the drawing, it is needless to say that the transporting direction can be changed at any position according to the facility of the field factory.

Fig. 2 is a view for showing the screw 3, and is a view seen from the upper direction in Fig.

As shown in the figure, the wings of the screw 3 are configured symmetrically with respect to the discharge port 4 as a center. That is, one of the first and second screws 15 and 16 is composed of a helical spiral of the cutting blade and a right-handed helical shape of the other. Therefore, when the chip 2 is inserted, the lower end of the hopper 1 is narrowed, so that the chips 2 are molten downward, and the lower portion is driven to the center by the screw structure of the screw 3. Thus, the chips 2 collected in the direction of the central discharge port 4 are pushed downward by the operation of the pressure cylinder 5.

The wings of the screw 3 not only collect the chips into the central outlet 4 but also serve to cut the chips. When the chips are cut by the screw (3) blade, the size of the chips becomes smaller, so the compression is better, the compression efficiency is higher, and the compression density of the compressed mass is increased.

Fig. 3 illustrates that the cutter 20 is installed on the screw shaft 21 of the screw 3. Fig.

As shown in the figure, a plurality of cutters 20 are installed at regular intervals in the screw shaft 21. [ The cutter 20 is made of a very strong material and is capable of cutting a round bar or the like as if it were cut with an ax while rotating together with the rotation of the screw shaft 21. [ In the drawing, it is exemplified that the long bar-shaped metal bar 25 is cut.

When working on chip compressors, wrenches, machined metals, machined metal wastes, machined wastes, etc., are also put into the automatic lathe in addition to chips generated during machining. 10), it is necessary to cut it.

4 is another embodiment of the present invention.

In the present embodiment, the hopper 1 is constituted by a chip carriage 32 for feeding chips.

A safety fence 30 for entering the chip truck 32 is provided and an entrance plate 31 is provided at the bottom of the safety fence 30 to provide an area sensor thereon. When the worker pulls the chip carriage 32 and enters the safety fence 30 or when the chip carriage 32 enters by mechanical transfer, the area sensor senses it and closes the door 35, So that the hopper 1 can be vertically climbed with the chip 34 inserted therein.

In addition, the area sensor installed on the entrance board 31 may be configured to stop the lift and to sound an alarm to prevent a safety accident when the operator enters the car without knowing it after the chip carriage 32 enters.

A wheel 36 is formed on the chip carriage 32 and is easy to move. It goes without saying that, after the chip carriage 32 is lifted by the lift 33, the chip 32 can be structured in various forms so as to be inclined as shown in the drawing and to be inserted into the hopper 1. Therefore, a detailed structure and description thereof will be omitted.

FIG. 5 is an enlarged view of FIG. 4, viewed from an angle of the other direction. A large amount of cutting oil is generated in the chip inserted into the hopper 1 and is collected on the floor. Particularly, when the compression by the compression cylinder 7 is performed, a lot of cut oil is generated as if oil is squeezed. Therefore, a collection passage for collecting these is made and collected. The recycled pulverized cutting oil is filtered and regenerated, thereby reducing environmental pollution, reducing costs, and recycling resources.

In Fig. 5, a coolant outlet 45 is formed and recovered. Alternatively, a conduit may be made here and configured to be transported back and forth over a long distance.

A control box 40 for operation and control of the apparatus is provided on the side of the chip compressor device. Further, a coolant recovery device 42 can be further provided to recover the coolant in situ. The coolant recovery device 42 may be any commercially available device having a built-in filter for filtering the coolant therein.

Fig. 6 is an application example of the present invention.

As shown in the figure, in the present embodiment, a chip transfer conveyor 50 is constructed in accordance with the facilities of the factory so that chips generated in the wheel shaper 51 are directly transferred along the chip transfer conveyor 50, (1).

As described above, according to the present invention, chips and various metal wastes to be disposed of are compressed and processed, so that the working environment is very clean, and space for storing and transporting chips can be greatly reduced. In addition, the compressed block can be recycled in various ways, which has the effect of recycling resources, and it is possible to solve the problem of the vehicle punk caused by the closed chips to the moving vehicles in the adjacent workplace.

In addition, the present invention is a highly efficient device that can be configured to automatically operate all systems when using a conveyor and chip carriage (32).

Although the present invention has been described as a chip compressor limited to a chip generated in a wheel mill of a railway vehicle, the present invention is not limited thereto and can be used also as a compressor for cutting chips generated in a machine tool such as a lathe drill or a milling machine And these are also to be construed as belonging to the technical scope of the present invention.
